Ciscoworks & subaccount administration

My boss is asking about the administrative ability of Ciscoworks where we would create sub-accounts (for lack of a better term) where we can create an non-admin account, and give that account access to only his own core switches for config archive access / manageability but not access to any other devices. He wants to be able to leverage a single installation of Ciscworks to manage not only corporate WAN routers, but also allow regional network administrators the ability to manage their core switches, but again, be able to view/manage their own devices. We have Ciscoworks 3.3 for Windows installed but I am not seeing this capability. He swears we'd had that capability in prior versions. I simply do not recall this feature. Is this a feature of 3.3 ?
